How much more stable (in kJ/mol), the benzyl radical when compared to a primary radical, is to be stated. The stability of benzyl and allyl radicals is to be compared. Concept introduction: Bond dissociation energy is the energy required in kJ/mol to break a bond into two radical fragments when the molecule is in the gas phase at 25°C. A radical formed with lesser bond dissociation energy will be more stable. To state: How much more stable the benzyl radical when compared to a primary radical. To compare: The stability of benzyl and allyl radicals.

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.
